1. Biogeographical Migration of Ginseng and Convergent Evolution in South America
From the perspective of traditional medicinal botany, Ginseng (Panax ginseng C.A. Meyer) and American Ginseng (Panax quinquefolius L.) have long been considered relict species confined to the cool temperate deciduous forests of the Northern Hemisphere, specifically within latitudes 30–48°N in East Asia and Eastern North America. As suggested by the research of Dr. Jun Wen, an evolutionary botanist at the Smithsonian National Museum of Natural History, these are congeneric species that diverged millions of years ago via the Bering Land Bridge, maintaining remarkable genetic conservation despite geographical isolation.1 However, from the viewpoint of 21st-century agronomy and the global bio-industry, the South American continent is emerging as a new land of opportunity—or an evolutionary testing ground—for the Panax genus, which was once the exclusive domain of the Northern Hemisphere.
Simultaneously, South America possesses indigenous plants that, while botanically unrelated to ginseng, exhibit strikingly similar physiological activities. Maca (Lepidium meyenii) from the high Andes and Pfaffia (Pfaffia glomerata) from the Amazon and Paraná River basins exemplify "convergent evolution." Despite belonging to different families, these plants have developed analogous adaptogenic mechanisms to resist extreme environmental stress, forming a competitive or complementary relationship with true ginseng in modern pharmacology.
This research report analyzes the introduction efforts of the alien species Panax and the industrialization process of native adaptogens in the vast ecological laboratory of South America. By integrating climate change, soil microbial ecology, immigration history, and global trade dynamics, this report presents an interdisciplinary analysis beyond a simple cultivation survey.
2. Introduction of True Ginseng (Panax) in South America: Ecological Adaptation and Agronomic Challenges
The attempt to cultivate Panax species in South America is not merely a transplantation of crops but a process of "ecological mimicry" aimed at recreating the Northern Hemisphere's forest ecosystem in the Southern Hemisphere.
2.1. Chile: Agronomic Analysis as the Optimal Cultivation Site in the Southern Hemisphere
Chile stands out as the South American nation with the highest success probability for cultivating Panax ginseng and Panax quinquefolius, being the only country where commercial-scale production is already underway. This is because Chile's geographical characteristics form a mirror image of the major ginseng producing regions in the Northern Hemisphere.
2.1.1. Micro-environmental Analysis of Climate and Soil
According to research by Jorge Harlowe Krimmel (2003) and technical reports from the Foundation for Agrarian Innovation (FIA), south-central Chile (Region VII Maule to Region X Los Lagos) perfectly satisfies the critical factors for ginseng cultivation: "chilling requirements" and drainage.4 Particular attention must be paid to the Trumaos soils distributed in the Andean foothills (Pre-cordillera). These volcanic ash-derived Andisols possess a unique porous structure that ensures the aeration essential for ginseng root respiration while maintaining excellent water-holding capacity. This acts as a physical barrier effectively suppressing root rot, the greatest challenge in ginseng cultivation.4
Furthermore, the climate of southern Chile provides distinct four seasons, allowing the accurate reproduction of the ginseng growth cycle (germination-growth-dormancy) with a six-month shift from the Northern Hemisphere. This grants a strategic advantage in supplying fresh ginseng to Northern markets (Korea, China, North America) during their off-season.
2.1.2. Soil Management Technologies for Sustainable Cultivation
Ginseng cultivation in Chile requires advanced soil management techniques beyond initial open-field farming. Recent studies on overcoming replanting failure in Northeast China provide significant implications for Chilean growers. Treating soil with maize or wood-derived biochar at a level of 20 t/ha has been shown to reduce the density of pathogenic fungi Fusarium spp. in the ginseng rhizosphere by 19–35%, while dramatically increasing the diversity of plant growth-promoting bacteria such as Burkholderia spp. and arbuscular mycorrhizal fungi.7 Since Chile's Trumaos soils already have high phosphate adsorption characteristics, adopting biochar-based soil amendment is crucial for increasing phosphate availability and preventing soil sickness caused by continuous cropping.
2.1.3. Regulatory Environment and Commercialization Status
The Public Health Institute of Chile (ISP) manages ginseng-containing herbal preparations under strict pharmaceutical or functional food regulations. Currently, ginseng products circulating in the Chilean market must undergo rigorous verification regarding the use of Panax ginseng C.A. Meyer roots and ginsenoside content.8 This contributes to establishing a brand image of "trustworthy quality" for Chilean ginseng in the international market. Local brands like 'Aura Vitalis' and products distributed through pharmacy chains (e.g., Easyfarma) are exploring export possibilities to neighboring South American countries beyond the domestic market.9
2.2. Argentina: Convergence of Experimental Research and Immigrant Networks
Ginseng cultivation in Argentina has developed along two axes: experimental approaches by national research institutions and small-scale community farming by Asian immigrants, rather than large-scale commercial agriculture.
2.2.1. The Role and Limitations of INTA
The National Agricultural Technology Institute (INTA) of Argentina, particularly the Balcarce Agricultural Experiment Station, has explored the potential of ginseng as a high-value alternative crop alongside staple crops like soybeans.11 The connection of European companies like 'Soria Natural' (Spain), which successfully cultivated ginseng in Europe, with South American research networks highlights the potential of Argentina's diverse climatic zones (especially the southern Pampas and northern Patagonia).12 However, as recent agricultural policies in Argentina have focused on the legalization and R&D of medical cannabis and industrial hemp, ginseng research, which requires a long cultivation period (4–6 years) and has a slow return on capital, has somewhat receded in priority.13
2.2.2. Applicability of Forest Farming
Research on wild-simulated ginseng by Purdue University and in Pennsylvania, USA, offers an important model for subtropical-temperate transition zones like Misiones province in Argentina. Forest farming practiced under the canopy of 20–30-year-old hardwood forests is a method that lowers initial investment costs and produces high-quality ginseng while preserving the natural ecosystem.15 In particular, the "stealth farming" method used by growers in Pennsylvania—harvesting only red berries and removing leaves to prevent theft and induce germination for the following year 17—could be a realistic strategy applicable in some rural areas of South America where security may be unstable.
2.3. Brazil: Japanese Immigration (Nikkei) and the Movement of Plant Genetic Resources
While tropical and subtropical climates dominate Brazil, the history of Japanese immigrants and the agricultural technologies they brought opened possibilities for introducing Panax species in the southern highlands.
2.3.1. Ivoti and the Legacy of the Japanese Colony (Colônia Japonesa)
The Japanese colony formed in the Ivoti region of Rio Grande do Sul was more than a settlement; it was an incubator for agricultural technology. Immigrants from Shiga Prefecture in the 1960s and 70s adapted not only fruit trees like grapes and kiwis but also medicinal plant seeds brought from their homeland.18 Although large-scale commercial cultivation of Panax ginseng was limited by climatic constraints, they maintained the tradition of 'Kampo' (Japanese herbal medicine), laying the intellectual foundation for systemizing local similar plants (Pfaffia) by naming them 'Brazilian Ginseng.' This demonstrates that the migration of ethnopharmacology—the knowledge system of handling plants—is as critical to the history of ginseng in South America as the physical movement of the plants themselves.21
2.3.2. Hideyo Noguchi and the Medical Research Connection
The footprint of Japanese bacteriologist Hideyo Noguchi, who was active in Brazil and across South America, indirectly fertilized the soil for medicinal plant research. His name remains on research centers like the Dr. Hideyo Noguchi Regional Research Center in Yucatán, Mexico, where modern screening of traditional medicinal plants for anti-parasitic efficacy is conducted.23 This research trend contributed to elevating South American indigenous plants from folk remedies to subjects of scientific verification, laying the groundwork for the globalization of Pfaffia and Maca, discussed below.
3. South America's Native Adaptogens: The Rise of Pfaffia and Maca
While true ginseng sought adaptation as a "stranger," the South American continent has evolved its own unique adaptogenic plants over thousands of years. Taxonomically distinct from Panax, these are the "Ginsengs of South America" that perfectly fulfill the definition of ginseng: 'enhancing non-specific resistance to stress.'
3.1. Brazilian Ginseng: Pfaffia (Pfaffia glomerata)
Belonging to the Amaranthaceae family, Pfaffia has been regarded by Brazilian indigenous people as a panacea, as indicated by its local name 'Para Tudo' (For Everything).
3.1.1. Floodplain Ecology and the Cultivation Revolution
Pfaffia adapted to the unique ecosystem of islands and floodplains in the Paraná River basin. Periodic flooding and rapid water level changes impose extreme stress on plants; Pfaffia developed a massive root system and potent secondary metabolites to cope with this.26
Historically dependent on wild harvesting (extractivism), a cultivation revolution occurred centered in the 'Querência do Norte' region of northwest Paraná. The organization of the Brazilian Ginseng Small Farmers Association (ASPAG) transformed indiscriminate harvesting into sustainable agriculture. Producing over 300 tons annually (2019-20), this region practices cyclical farming using only the nutrients provided by river sediment without chemical fertilizers or pesticides.26 It has established itself as one of the most profitable crops per hectare for small family farms.
3.1.2. Biochemical Characteristics: Harmony of Saponins and Ecdysteroids
Pfaffia is called 'Brazilian Ginseng' not only for its root morphology but also for the potency of its components.
Beta-ecdysone: A key marker component of Pfaffia. Structurally similar to insect molting hormones, it exhibits powerful anabolic effects in mammals. It promotes muscle growth and physical strength, gaining popularity in the sports nutrition market as a natural alternative without steroid side effects.28
Pfaffosides: Triterpenoid saponins similar to Panax ginsenosides, reported to inhibit cancer cell proliferation and regulate blood sugar.29 Research on anti-cancer properties, particularly melanoma inhibition, is active.
3.1.3. Export Imbalance and Value-Added Challenges
Brazil is the dominant global supplier of Pfaffia, but it faces structural industrial issues. Despite exporting over 11,000 tons of raw material in 2011, most was in unprocessed root or powder form. Studies indicate that exporting in extract form can generate over 10 times the added value compared to raw material.31 Furthermore, while high-value products using Pfaffia extracts are sold in advanced markets like Japan, local Brazilian farmers are exposed to raw material price volatility. The introduction of eco-friendly, high-efficiency extraction technologies such as Supercritical Fluid Extraction is urgent to resolve this.33
3.2. Peruvian Ginseng: Maca (Lepidium meyenii)
The Puna grasslands of the Andes (above 4,000m) represent the highest limit for agriculture on Earth. Maca, a Brassicaceae plant, is a biological miracle wrought by this harsh environment.
3.2.1. Adaptation to Extreme Environments and the Secret of the Hypocotyl
The environment where Maca grows is dominated by intense ultraviolet (UV) radiation, low oxygen partial pressure, temperature fluctuations between freezing and thawing, and strong winds.34 To withstand such oxidative stress and physical damage, Maca adopts a rosette shape, flattening its leaves against the ground, and stores nutrients and defense substances in its enlarged hypocotyl (root). This process concentrates unique bioactive substances such as glucosinolates and macamides.34
3.2.2. The Maca Boom and the Shadow of Biopiracy
Since the 2010s, exploding demand for Maca, centered on the Chinese market, brought both unprecedented economic opportunity and crisis to Peru. Exports grew from $1.4 million in 2001 to tens of millions of dollars in just a decade.36 While Maca became a key item alongside quinoa and blueberries in Peru's non-traditional agricultural exports (surpassing $11.5 billion in 2023-2024),37 this success was accompanied by "biopiracy." Chinese traders swept up raw roots in Peru or illegally smuggled genetic resources to attempt mass cultivation in places like Yunnan, China. This undermined the price-setting power of Peruvian farmers and devalued indigenous genetic resources. In response, the Peruvian government (ADEX, PromPerú) has banned the export of unprocessed Maca and is reinforcing sustainable export models based on 'Biotrade' principles.39
3.2.3. Global Market Statistics and Outlook
As of 2024, the global Maca powder market is valued at approximately $600 million and is projected to reach $1.2 billion by 2033.41 The main export destinations are the United States (over 31% share), the Netherlands, and China. In the Organic Maca Powder market specifically, Peru competes with Panama and China but maintains quality competitiveness through the 'Andean Origin' premium.42

4. Comparative Pharmacology and Biochemical Convergence Analysis
As a specialist researcher, comparing the three major ginsengs of South America (True Ginseng, Pfaffia, Maca) at the molecular pharmacological level is essential for determining the industrial suitability of each plant.
4.1. Differences in Adaptogenic Mechanisms
All three plants increase stress resistance, but their pathways differ.
Panax: Ginsenosides have a structure similar to steroid hormones, acting directly on the Hypothalamic-Pituitary-Adrenal (HPA) axis to regulate cortisol levels.43 P. quinquefolius (American ginseng), in particular, has high Rb1 content, offering excellent sedative and neuroprotective effects.44
Pfaffia: Beta-ecdysone induces molting in insects but activates the PI3K/Akt pathway in humans, stimulating protein synthesis in muscle cells. This enables "non-hormonal anabolic action," increasing physical vitality without artificially disrupting hormone levels.29
Maca: Macamides (N-benzylamides) are structurally similar to the neurotransmitter anandamide. They are believed to inhibit the FAAH enzyme in the endocannabinoid system, preventing the breakdown of anandamide, thereby exhibiting neuroprotective, pain-relieving, and mood-lifting effects.35
5. Conclusion and Future Outlook: Integration and Innovation
Ginseng research in South America is not merely a geographical expansion of Northern Hemisphere crops but a site where human agricultural history and ecological wisdom converge.
Alternative to Climate Crisis - Chile and Argentina: As traditional ginseng growing regions in the Northern Hemisphere are threatened by warming, southern Chile and northern Patagonia in Argentina could become a "Second Ark" ensuring the stability of the global ginseng supply chain. To achieve this, the establishment of low-input, high-efficiency farming methods such as biochar-based soil amendment and Wild-simulated farming is essential.
Advancement of Indigenous Resources and Ethical Trade: Brazilian Pfaffia and Peruvian Maca have already moved beyond the raw material market. They must now leap to the phytopharmaceutical level through the development of Standardized Extracts and the acquisition of clinical data. Furthermore, a sustainable industry can only be achieved when the intellectual property rights of local farmers and indigenous people are protected through benefit-sharing models based on the Nagoya Protocol.
Necessity of Convergence Research: What synergies would arise if Korean ginseng processing technologies (e.g., nine-steaming-nine-drying, fermentation) were applied to Pfaffia or Maca? Is a new sports supplement combining Pfaffia's ecdysone and ginseng's saponins possible? At the intersection where South America's rich genetic resources meet Asia's ancient processing technologies, we anticipate the birth of the next generation of global blockbuster natural drugs.
South American ginsengs are no longer "imitations." Whether introduced Panax or indigenous Pfaffia/Maca, they offer unique solutions for human health from their respective ecological niches.
